ON COI^EOPTERA. FROM THE CAMEROONS. [Feb. 1, 



aquans ; labrum tenue, nnguste reflexuin ; columella oblique 

 contorta, expansa, umbilicum semiobtegens. Lonyit. 30 millin., 

 diam, 16. 



Gihbus (Edentulina) johnstoni. 



This is a smaller species than G. martensi. Smith, or G. insignis, 

 Pfeiffer. It is also much more finely striated than the former and 

 of a different shape, and has no plication on the columella as in the 

 latter, which is an imperforate shell. 



8. On some Coleopterous Insects collected by Mr. H. H. 

 Johnston on tlie Cameroons Mountain. By Charles 

 O. Waterhouse. 



[Eeceived January 31, 1887.] 



The following Coleoptera were obtained by Mr. H. H. Johnston 

 at altitudes from 8000 to 10,000 feet on the Cameroons Mountain : — 



1. ScARiTES ROTUNDicoLLis, Murray. 



2. Two female examples of a Lamellicorn, apparently one of the 

 Trichiidae ; 7 lines long, black, with deeply impressed striae on the 

 elytra. It is very desirable to look for the male of this insect, which 

 would doubtless be quite different in colour and perhaps in form. 



3. Batomene MULTispiNis, Bates (Ent. Mo. Mag. xxi. 1884, 

 p. 15), described from the Cameroons. 



4. Temnoscelis biemarginatus, Chevr. A single specimen 

 in the British Museum from Old Calabar. 



5. A species of Otiorhynchus closely resembling the European 

 O. bisulcatus, but having the humeral angles slightly prominent, 

 and the disk of the thorax with a short ridse. 



6. Epilachna, sp. ? (In pieces.) 



Erom "Cameroons Mountain, 2000 feet, Oct. 1886:"— 



7. Ceratorhina torgiuata, F. A common West-African 

 species.
